JAMES NUTTALL, OF BURY, ENGLAND.

APPARATUS FOR CUTTING BAGS, ROPES, AND THE LIKE.

Apnlicatinn filed June 18.

T 0 all whom it may concern:

Be it known that I, JAMES NUTTALL, a

subject of the King of Great Britain and Ire' land, of 171 WValmersleyroad, Bury, in the county of Lancaster, England, engineer, have inventedcertain new and useful Im provements in Apparatus for Cutting Rags,Ropes, and the Like, of which the following is a specification.

My invention relates to apparatus for cutting rags, ropes, and the like,in which apparatus the material is first cut in one direction byguillotine, or rotary, cutters, and then is fed to, and cut in the otherdirection between, a fixed, or dead, knife and spiral knives on a rotarycarrier, and the object of my invention is to simplify such apparatusand make it so that it acts very efficiently, and I provide meanswhereby the aforesaid fixed, or dead, knife can be used for a longerperiod than hitherto.

I will describe my invention with reference to the accompanyingdrawings.

Figure 1 is a side elevation and Fig. 2 a

plan of mechanism in accordance with my invention. Fig. 3 is alongitudinal section and Fig. 4 a plan of a fixed, or dead, knife ashereinafter described.

I arrange a fixed, or dead, knife A and a rotatory knife consisting ofspiral blades B on a rotary carrier C, between which knives the materialis cut after it has been cut by the first cutters D, which are shownasbeing serrated disk-cutters, although they may be guillotine knives, orcutters, of other suitable kind. The fixed, or dead, knife A is in aposition slightly above the center on which the rotary knife turns, andparallel with the said rotary knife, and I rotate the rotary knifecarrier C so that the blades B carried by it pass the fixed, or dead,knife A in an upward direction so that the material is cut upwards andthrown over the top of the rotary knife blades B. The material isconducted from the first cutters D to the said fixed, or dead, knife androtary knives by an apron, or creeper, E, one of the rollers (F) overwhich the said apron, or creeper, passes be ing beneath the fixed, ordead, knife A and being held up to its working position, which may bedone by means of springs, or, as shown, by means of weighted levers Gkeyed to a shaft H to which are fixed arms 9 connected to links 9carrying the axle f of the roller F, which axle is guided at each end inguides t in projections I from the underside Specification of LettersPatent.

of the carrier I. The roller F and the part of the apron or creeper, Ewhich passes over it act as a feeder as well as a carrier for thematerial being operated upon and the aforesaid springs, or arrangementof weighted levers, arms and links allow the roller F and the part ofthe apron, or creeper, E passing over it to rise and descend accordingto the amount of material passing between the apron, or creeper, E andthe underside of the fixed, or dead, knife, A. By this means thematerial is fed directly to the fixed, or dead, and rotary, knives,without having to bend the said material, which is an especial advantagewhen stiff material is being operated on.

The fixed, or dead, knife A and its means of attachment I arrange sothat the said knife A can be readjusted and fixed in position for eitherof its four longitudinal edges (1, 2, 3, 4, Fig. 1) to be brought intoposition to act as a cutter, the grinding of the two edges on either ofthe sides of the knife being effected at one operation.

The fixed, or dead, knife A is carried by a holder I fixable to the mainframe J by screw bolts and nuts t passing through slot ted holes i andwhen the nuts of these screw bolts are slackened, the said holder I isadjustable relatively to the rotary blades B, by means of screws Kpassing through screwnuts 76 on the main frame J, the roller F being atthe same time adjusted as the guides i of its axle f are rigid with theholder I. The said fixed, or dead, knife A is secured to the said holderI by means of screw bolts L passing through holes a in the fixed, ordead, knife, the said holes a being so arranged symmetrically with thesides and ends of the said knife A that whether the said knife A beturned end for end, or be reversed, so that what was the upper side isbrought undermost, the holes a therein will still coincide with theslotted holes 01 in the holder I for the securing screw bolts L.Adjusting screws M passing through nuts i on the holder I bear on therear of the fixed, or dead, knife A to adjust it in the holder Irelatively to the rotary blades B and the roller F, and the said knife Acan be held in its adjusted position by rods N passing through theholder I and provided at one end with the locking nuts n and at theother end with turned-in, or hooked, ends n engaging with central holesa in the ends of the fixed, or dead, knife A. The screw bolts L by whichthe fixed, or

dead, knife A is secured to the holder I are provided with heads Z whichengage in countersinks a around the holes a in the fixed, or dead, knifeA, so that the side of the said knife A which is undermost has noprojections from it. The said heads Z and the countersinks a with whichthey engage are preferably cone-shaped, as shown. The countersinks a aremade on each side of the knife A so as to allow of the engagement of theheads I of the screw bolts L whichever side of the said knife A isundermost. A groove and feather arrangement a, may be used to preventthe bolts Lturning in the openings a in the fixed, or dead, knife A, or,for this purpose, the heads Z of the said screw bolts L and the recessestherefor in the fixed, or dead, knife A may be made non-circular.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In an apparatus for cutting rags, ropes and the like,cutters to cut the material in one direction, and cutters to cut thematerial in another direction, said second set of cutters comprising afixed knife and a knife ro tated past said fixed knife in an upwarddirection, said fixed knife being arranged in a plane only slightlyabove the axial plane of the rotary knife, substantially as described.

2. In apparatus for cutting rags, ropes, and the like, the combinationwith a fixed knife and a knife rotated past the fixed knife in an upwarddirection, of a creeper passing over a counterweighted roller beneaththe fixed knife, so as to act both as a carrier and the like, cutters tocut the material in one direction, cutters to cut the material at anangle to said first cut and means yieldingly supported to convey andfeed the material from the first to the second set of cutters.

5. In apparatus for cutting rags', ropes, and the like, the combinationwith a rotary knife and a fixed knife secured in place by meanssymmetrically arranged for reversal of its faces and ends, of adjustingscrews and screw rods and nuts, the said rods having hooked endsengaging with central holes in the ends of the fixed knife;substantially as hereinbefore described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES NUTTALL.
